Int search vector int & nums int target
This is the first problem on binary search at leetcode. We're asked to return the index of a target at a given array. My first attempt at a solution was the following: class Solution { public: int search (vector& nums, int target) { int result = -1; for (int i = 0; i < nums.size (); i++) { if (nums [i] == target) result = i; } return ... WebSep 25, 2024 · You can assume that the given target number must exist in the array. Implement the Solution class: Solution (int [] nums) Initializes the object with the array nums. int pick (int target) Picks a random index i from nums where nums [i] == target. If there are multiple valid i's, then each index should have an equal probability of returning.
